Title: Liquid crystal display device
Inventor: OKITA MITSUTAKA
IPC: G02F1/1335
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To suppress a decrease in contrast in a direction at right angles to liquid crystal molecules and to obtain superior field angle characteristics even under a back display condition wherein field angle dependency is large. SOLUTION: Uniaxial phase difference plates 4b, 4u, and 6 which have positive optical anisotropy are arranged so that their main axes do not cross the positive projection direction of liquid crystal molecules of the liquid crystal cell of a liquid crystal layer 1 to substrates 3b and 3u, but are almost in parallel to, specially, the direction of the axis of polarization of an analyzer 8, and consequently a high contrast can be obtained over an extremely wide field angle range.

Title: Surface acoustic wave filter
Inventor: NAKAZAWA MICHIYUKI
IPC: H03H9/145
Filed: 1993-03-08
Abstract: PURPOSE:To reduce the loss and the in-band ripple and to miniaturize a device by alternately arranging input and output transducers, which have plural electrode fingers arranged at regular intervals, on the same surface acoustic wave propagation line. CONSTITUTION:A surface acoustic wave wavelength lambda is determined by electrode finger pitches of input transducers 11 to 14 and output transducers 21 to 23. Reflectors 31 and 32 are arranged on both of outermost sides of groups of transducers 11 to 14 and 21 to 23. Since respective electrode finger pitches of transducers 11 to 14 and 21 to 23 are equal and they are alternately arranged on the same surface acoustic wave propagation line, the loss is reduced. Since reflectors 31 and 32 have plural short strip conductors and are arranged on both of outermost sides of transducers 11 to 14 and 21 to 23, the device is miniaturized. Relations between the wave-length lambda and distances (d) from the centers of electrode fingers adjacent to reflectors 31 and 32 to the centers of short strip conductors of reflectors 31 and 32 are selected to reduce the in-band ripple.

Filed: 1994-04-12
Abstract: PURPOSE:To shorten the test time and to increase the overall working speed of a system by providing an erase/write/read control part to simultaneously carry out two or more of erasion, write and read functions in different memory blocks. CONSTITUTION:In a write mode, the write signal/data consisting of a control signal 2, the data 3 and an address 4 are given to an instruction analysis/status data generation part 6 from the outside. The part 6 confirms whether the operating memory block is erased or not and then sends an operation start signal to a write control part 8 through a bus 9i. The part 8 sends a using request of the bus 9 to the part 6 by a request signal 8b and receives the permission in an acknowledge signal 8c for use of the bus 9. Thus the part 8 successively transmits the signals to the bus 9, a latch circuit 11, a bus 12 and a memory block 10 and carries out a write operation. Thus, for example, a read operation can be carried out in a memory block 10c while the erase and write operations are carried out in the memory blocks 10a and 10b respectively.

Title: Fluorometric device
Inventor: NAKAYAMA YOSHIHIKO
IPC: G01N23/225
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To automate the fluorometry in a plurality of measuring points having different measuring conditions by providing a sample stage movement-controllable from a device controlling computer. SOLUTION: A sample stage 8 can be movement-controlled from a device controlling computer so as to successively emit an exciting energy beam to a plurality of designated coordinates on the sample stage 8, and the measurement condition can be preliminarily registered in conformation to each designated coordinate. Further, when the movement of the sample stage 8 to a designated coordinate is ended, the measurement condition registered in conformation to the designated coordinate is automatically set from the device controlling computer. Otherwise, after the movement of the sample stage 8 is ended, the measurement condition is automatically set at the point of time when the start of measurement is instructed to start the measurement.  According to this means, in measurement, the measurement condition is automatically changed according to the change of the position to emit the electron beam. Therefore, measurement in a plurality of measuring points having different measurement conditions can be automatically performed by controlling the execution of a series of measuring operations such as the movement of the sample stage 8 to the designated coordinate from the device controlling computer.
